当我在浏览器上调整大小时，为什么我的页面会滚动？

Question

我正在做一个仪表板，但遇到了问题。当我调整窗口大小时，它会自行滚动。一切都是响应式的，但我不明白为什么它会滚动。感谢您 ！

将您的 profileScroll.js 文件更新为以下代码。

当您调整浏览器大小时，滚动位置会发生变化。由于您使用它来制作动画并计算页面的位置，因此在调整窗口大小时需要重新计算它们。

window.addEventListener('load', function () {

    var delayInMilliseconds = 1;

    

    function updateScrollPosition() {

      if (window.scrollY != document.getElementById("homePage").offsetTop || window.scrollX != document.getElementById("homePage").offsetLeft) {

            window.scroll(document.getElementById("homePage").offsetLeft, document.getElementById("homePage").offsetTop);

        } else {

            document.documentElement.style.animationFillMode = "forwards";

            document.documentElement.style.animationDelay = "1s";

        }

        document.documentElement.style.scrollBehavior = "smooth";

    }

    setTimeout(function () {

        updateScrollPosition();

    }, delayInMilliseconds);

    document.getElementById("profileButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("profilePage").offsetLeft, document.getElementById("profilePage").offsetTop);

    });

    for (i = 0; i < document.getElementsByClassName("returnToHomePage").length; i++) {

        document.getElementsByClassName("returnToHomePage")[i].addEventListener("click", function () {

            window.scrollTo(document.getElementById("homePage").offsetLeft, document.getElementById("homePage").offsetTop);

        });

    }

    document.getElementById("mailButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("mailPage").offsetLeft, document.getElementById("mailPage").offsetTop);

    });

    document.getElementById("noteButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("notePage").offsetLeft, document.getElementById("notePage").offsetTop);

    });

    document.getElementById("gameButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("gamePage").offsetLeft, document.getElementById("gamePage").offsetTop);

    });

    document.getElementById("calendarButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("calendarPage").offsetLeft, document.getElementById("calendarPage").offsetTop);

    });

    document.getElementById("voiceButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("voicePage").offsetLeft, document.getElementById("voicePage").offsetTop);

    });

    document.getElementById("buyButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("buyPage").offsetLeft, document.getElementById("buyPage").offsetTop);

    });

    document.getElementById("paramsButton").addEventListener("click", function () {

        window.scrollTo(document.getElementById("paramsPage").offsetLeft, document.getElementById("paramsPage").offsetTop);

    });

    window.addEventListener('resize', function(){

      updateScrollPosition();

    });

});

但我会让它更通用一些：

window.addEventListener('load', function() {

const delayInMilliseconds = 1;

let currentPageId = 'homePage';

function scrollToPage(pageId) {

    currentPageId = pageId;

    window.scrollTo(document.getElementById(pageId).offsetLeft, document.getElementById(pageId).offsetTop);

}

setTimeout(function() {

    document.documentElement.style.animationFillMode = 'forwards';

    document.documentElement.style.animationDelay = '1s';

    document.documentElement.style.scrollBehavior = 'smooth';

    scrollToPage(currentPageId);

}, delayInMilliseconds);

let actions = [

    { buttonId: 'profileButton', pageId: 'profilePage' },

    { buttonId: 'mailButton', pageId: 'mailPage' },

    { buttonId: 'noteButton', pageId: 'noteButton' },

    { buttonId: 'gameButton', pageId: 'gamePage' },

    { buttonId: 'calendarButton', pageId: 'calendarPage' },

    { buttonId: 'voiceButton', pageId: 'voicePage' },

    { buttonId: 'buyButton', pageId: 'buyPage' },

    { buttonId: 'paramsButton', pageId: 'paramsPage' },

];

// Make sure you use `let` instead of `var`. The scope of `var` is global. 

for (let i = 0; i < actions.length; i++) {

    document.getElementById(actions[i].buttonId).addEventListener('click', function() {

        scrollToPage(actions[i]);

    });

}

// Check all document clicks, if the target has the class 'returnToHomePage' go back to home page.

// This way you don't have to loop over the buttons

document.addEventListener('click', function(event) {

    if (event.target.classList.contains('returnToHomePage')) {

        scrollToPage('homePage');

    }

});

window.addEventListener('resize', function() {

    scrollToPage(currentPageId);

});

});
